Compact Flash

Looking for a good compact flash for sports photography for my 300 D Canon. I shoot mainly in RAW. I see people talking on here that they only get 150 pics with a 1g card, but Im currently getting 70 RAWS on my SanDisc 256 card (wouldnt it be more like 280 raw pics on a 1g?). Anyway, Im an amateur, only taking 150 or so pics at a time. I guess what Im asking is your feelings on the best 512 cards as far as price and read/write speeds. I only wish to spend 50$ or so (unless you pursuade me :shock: ). I see on Newegg.com a PQI 512 card with 20 mbytes per second for $39 US.

Thanks again!
